SPECIIEICQTION forming part of Letters Patent No. 347,3] 2, dated August17, 1886.

Application filed May 4, 1886.

To all whom it may concern:

Be it known that I, NELsoN BARNESLEY, a citizen of the United. States,residing at Esrom, in the county of Barton and State of Missouri, haveinvented new and useful Improvements in Chorus, of which the followingis a specification.

My invention relates to improvements in rotary churns; and it consistsof the peculiar and novel construction and arrangementof the variousparts for service, substantially as hereinafter fully set forth, andparticularly pointed out in the claims.

The object of myinvention is to provide an improved churndasher whichshall be very simple and strong in construction, and which shall becapable of creating a violent and rapid agitation in the vessel amongthe particles of the cream to complete the churning thereof in a veryshort time; and a further 0bj ectof my invention is to provide areceptacle with breaker'strips that serve efficiently to in-' crease theagitation among the particles of the cream, the dashers being rotated inthe same planes of rotation by mechanism which is simple and effective,all as hereinafter described.

In the accompanying drawings, Figure 1 is a vertical sectional viewthrough a churnbody, showing my invention in elevation. Fig. 2 is a likevertical section view through the apparatus on the line a: w of Fig. 1.Figs. 3 and 4 are detached perspective views of the rotating dashers.

Referring to the drawings, in which like letters of reference denotecorresponding parts in all thefigures, A designates the churn body thestandard D, which is provided with the.

lugs d, that are secured at their lower endsby bolts or screws to thecover and at their 111)- per ends with a bearing or box, at, for theSerial No. 201,082. (No model.)

driving-shaft E, that is jonrnaled therein and carries a crank-handle,e, for its convenient rotation by hand, and a master gear-wheel, F, thatis arranged to one side of the standard and secured at one end of theshaft. This master gear-wheel meshes with and rotates a pinion, ii, thatis jonrnaled on a shaft, h, the lower end of which is journaled in thecover 0, while the upper end thereof is jonrnaled in a bridge-plate, D,of the standard D. The pinion h meshes with and rotates the pinions iandj of the vertically-disposed dasher-staffs J. I of the dashers I and J,the said shafts being extended through the bridge-plate D and the cover0 of the churn. WVhen the mastergear is rotated by the action of thecrank and driving-shaft, it rotates the pinion h, and the latter rotatesthe pinions z and j in one direction simultaneously, so that the dashersI and J are rotated in the same plane, as will'be very readilyunderstood.

The dasher-staff I is extended the entire length of the churn body orvessel, so that the lower. end thereof is out of contact with the bottomof the said vessel, and at its upper and lower ends the dasher staff orrod is provided with horizontal cross-heads k and 7c, the free ends ofwhich carry integral arms or beaters Z, that are arranged parallel withthe dasherstaif and themselves, the free ends of the beaters orarms'being separated from the arm adjacent thereto on the same side ofthe dasherrod by an intermediate space.

It will be observed that a space is provided between the side arms orbeaters of the dasher I and the staff thereof, through which work theside beaters of the dasher J, and between the ends of the dasher-arms orbeaters lainother space is provided for the free passage therethrough ofthe cross-head of the dasher J, as will be more fully describedpresently.

The dasher rod or staff of the dasher J extends into the churn-bodyabove one-half of the length of the latter, and at itslower end it isprovided with a cross arm or head, m, and the free ends of thecross-head m are provided with vertical arms or beaters n, that arearranged parallel with the dasher-staff and with each other, the arms atextending nearly the entire length of the churn-body.

The arms a are adapted to pass between the arms I and the dasher-staff lof the dasher I when the dashers are in one of their positions, and thecross-head m passes through the space between the free ends of twoadjacent arms, Z, while the armsZ move through the space intermediate orthe dasher-rod and the arms a of the dasher J, as will be very readilyunderstood. The abovedescribed operation or movement of the parts takesplace each time the dashers have made a half-revolution, and at the endof the remaining half of the revolution the dashers are arrangedparallel with each other, and are separated from each ily understoodfrom the foregoing description,

taken in connection with the drawings.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination of the vessel hai-"ing the breakerstrips inclosedwithin the same and arranged at diametrically opposite points, thecover, the standard secured to thecover and having the bearing, thedriving-shaft journaled in the bearing, and having the mastergear andthe eranlehandle, the pinion h, j ournaled on a shaft that is secured ina bridgeplate of the standard, the dashers I and J, having their staffsextended through the cover and bridge-plate, and provided with thepinions'iandj that mesh with the pinion 71, which rotates themsimultaneously and in the same direction, the dasher ll having; thecross heads at its ends, each carrying the vertical blades, and thedasher J having the cross-hcad at its lower end, which is provided atits free end with vertical extended arms, the whole arranged andcombined substantially as de scribed.

2. In a churn, the combination of the dashers I J, arranged to rotatesimultaneously and intercept the path of a circle described by oneanother, the dasher I having, the cross-heads provided at their freeends with verticallydisposed arms I, and the dasher J, having a singlecross-head, m, at its lower end that is adapted to pass between theextremities of the arms carried by the cross-heads k 7;, and pr0- vidcdwith vertical arms a, substantially as described, for the purpose setforth.

In testimony that I claim the lbregoing as my own I have hereto afilxedmy signature in presence of two witnesses.
